A multi-wavelength Erbium-doped fiber (EDF) laser based on four-wave-mixing is proposed and experimentally demonstrated. The 5 km single mode fiber in the cavity enhances the four-wave-mixing to suppress the homogenous broadening of the erbium-doped fiber and get the stable multi-wavelength comb. The lasing stability is investigated. When the pump power is 300 mW, the fiber laser has 5-lasing lines and the maximum fluctuation of the output power is about 3.18 dB. At the same time, a laser with 110 m high nonlinear fiber (HNFL) is demonstrated. When the pump power is 300 mW, it has 7-lasing lines (above -30 dBm) and the maximum fluctuation is 0.18dB.
提出并通过实验证明了一种基于四波混频的多波长掺铒光纤（EDF）激光器。腔内5公里的单模光纤增强了四波混频，以抑制掺铒光纤的均匀展宽并获得稳定的多波长梳状谱。研究了激光的稳定性。当泵浦功率为300 mW时，光纤激光器有5条激光线，输出功率的最大波动约为3.18 dB。同时，展示了一个带有110米高非线性光纤（HNFL）的激光器。当泵浦功率为300 mW时，它有7条激光线（高于-30 dBm），最大波动为0.18dB。
